Definitions
- the invention relates to a longitudinal element, in particular for a pulling or suspension means, according to the preamble of claim 1.
- a longitudinal element as a core rope discloses high strength plastic fibers made of a twisted monofilament bundle or a plurality of twisted monofilament bundles and having an outer layer of steel wire strands.
- the Monofilbündel be stretched under diameter reduction and held in this state by a, in particular braided, sheath.
- the elongation of the core rope is reduced under load, so that the load distribution between the steel cross section and the plastic cross section of the rope improves.
- the cable has an intermediate layer made of an elastic plastic, in which the steel wire strands are pressed in at a distance from each other, such that the outer layer stretches under load and contracts radially.
- Nets for example, known as ring nets or braids are characterized by the fact that they have a high tensile strength and a good deformability, and therefore can be loaded to a considerable extent.
- a protective net is known as a high-strength wire mesh, preferably for a rockfall protection or for securing an earth surface layer which consists of helically bent high-strength steel.
- braided wires and has a three-dimensional structure.
- the helically bent wires have a pitch angle and a length between two bends that determine the shape and size of the mesh of the wire mesh.
- the object of the present invention was to provide a longitudinal element, in particular for a tension or suspension element, for different applications, such that it has similar properties to a longitudinal element made of wires, and this weight optimization is achieved, with a perfectly functioning operation should be permanently ensured even in harsh environmental conditions.
- the metal shell of the respective longitudinal element is mounted on the outer circumference of the core such that a gas-, UV-, light- and / or water-impermeable layer is formed for these fibers.
- these high-strength fibers which are very light in relation to their strength, are protected in several ways, namely against moisture, moisture, UV light and other environmental influences and, moreover, through the composite with the metal shell an approximately the same Elongation arises.
- the metal sheath protection against transverse pressures on the fibers is achieved. This leaves the high-strength properties of the tension or support element overall in a sustainable way.
- this inventive design of the wire-shaped longitudinal elements results in a significant advantage that they are suitable for a variety of applications.
- these longitudinal elements are suitable for tension or support elements, such as spiral or stranded cables, prestressing supports or the like, in particular for the cable car and support area. These longitudinal elements can be used both in running as well as standing rope constructions.
- these longitudinal elements but also in electrical cables, telecom cables or parts, can be used by these a perfectly functioning operation is permanently ensured even in harsh Hydraulic ⁇ conditions.
- Other applications with such wire-shaped longitudinal elements are possible in the context of the invention, in which high tensile forces and high environmental resistance are required with low weight, this advantageous at the same time Biegetrag Quant.
- These longitudinal elements can also be parallel to each other, ie. not stranded, used.
- Fig. 1 shows a longitudinal element according to the invention in perspective
- Fig. 2 shows a cross section of an inventive as a spiral egg! trained Switzerland- or Tragmittei with verlitzten longitudinal elements of Fig. 1;
- FIG. 3 shows a cross-section of an inventive trained as a stranded rope train or Tragmittei.
- FIG. 4 shows a cross-section of an inventive trained as a closed rope tension or support means.
- FIG. 5 shows a cross section of a telecom cable with wire-shaped longitudinal elements according to the invention
- FIG. 6 shows a cross-section of an electric cable with d rahtförmigen longitudinal elements according to the invention
- Fig. 7 shows a cross-section of a further variant of an electric cable with integrated wire-shaped longitudinal elements; a view of a network shown in part as a braid, which is braided from helical L jossseie- inventive inventive Lssenseie-;
- FIG. 1 a perspective view of a safety net for the protection area, which consists of interlocking annular longitudinal elements;
- Fig. 1 shows a longitudinal member 13, by means of which in particular tensile and / or bearing forces can be absorbed even for very high forces. It can be used for a variety of areas, as shown below with reference to the various embodiments.
- this longitudinal member 13 formed as a wire is produced from a core 12 made of a plurality of high-strength fibers 11 and from a metal shell 15 surrounding this core 12, preferably steel or stainless steel.
- the metal mantle 15 is arranged around the core 12 formed with the fibers 11 and is arranged along the longitudinal extent of the longitudinal belt.
- tes 1 3, for example, by a weld seam 1 5 'held at the abutting surfaces of the side edges connecting.
- the metal shell 1 5 is provided with a certain bending and / or buckling resistance in order to achieve an adapted flexibility or a sufficient impact or pressure resistance of the longitudinal element as a whole.
- the metal sheath can be provided with a variable sheath cross-section along its longitudinal extent and likewise different types of high-strength fibers 11 can be used in order to achieve the optimum design of the specific use for the different requirements.
- the metal shell may consist of a second or multiple shell layers. To achieve the variable cross-section, at least one second cladding layer may be applied to a first cladding layer at certain intervals.
- the metal jacket 15 is formed as a further characteristic of the invention with a cylindrical outer surface. Of course, this outer surface may be different depending on the needs.
- a filling layer 14 such as a gel or an adhesive, a bandage or a mixture thereof is inserted.
- a different degree of hardness of the filling layer can be used in order to achieve different transverse pressure and joining properties of the longitudinal element.
- the degree of solidification produced in the manufactured longitudinal element can be designed differently depending on the application in order to optimize the transverse compressive stiffness of the same.
- the metal shell and / or the core may be provided with a surface roughening. This results in a better connection between the fibers 1 1 and the inside of the metal jacket 15 by friction or by gluing in order to achieve a nearly uniform stress / strain profile.
- the metal sheath could also be preferably seamless as a tube into which the fibers could be introduced.
- the metal sheath could just as well be realized by at least one metal band wound around the core, which at the overlapping or abutting side edges is welded together by gluing, gluing or a similar connection or even without such a combination. could be added.
- material for the metal cladding it is suitable for a corrosion-resistant material, for example a galvanized steel, but also aluminum or copper with non-corrosive properties.
